BK like it or not, is a successful businessman.
His modus operandi is to "sweat assets".
This means you invest sufficient to gain ownership, but beyond that you work the asset as hard as possible without further investment. In the case of his theatre interests that results in profits/dividends from a low cost/low capex business (usually one that defers capital investment as far as it possibly can) - in the case of Everton, find a manager (managers) who can build a low cost team that consistently out-performs more expensive competition.
Capital and investment return achieved by selling "sweated" assets to third party.
